SHUTTER MECHANISM.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed May 3, 1915. Serial No. 25,377.

To all whom it may concern:

Be it known that 1, JOHN T. AUsTIN, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shutter Mechanism, of which the following is a specification.

This invention relates to shutter mechanism, the object of the invention being to provide simple and effective means of the character set forth by which one or more shutters can be tightly closed irrespective of the fact that the same may be warped or other conditions be present which ordinarily would preclude the result mentioned.

\Vhile shutter mechanism involving my invention can be employed with advantage in many different connections, the same is of particular utility when used in organ construction.

In the drawings accompanying and forming part of the present specification, I have shown in detail one of the several convenient forms ofembodiment of the invention which to enable those skilled in the art to practice the same will be set forth fully in the following description. I do not restrict myself to this disclosure; I may depart therefrom in sey'eral respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a front elevation of shutter mechanism involving my invention, the intermediate portion of the shutters there shown being broken away and the end portions of the shutters and the side supports for said shutters being brought toward each other. Fig. 2 is a vertical section on the line of Fig. 1, looking in the direction of the arrow. Fig. 3 is a top plan view, and, Fig. 4 is a side elevation of a bracket.

Like characters refer to like parts throughout the several views, which it will be noted are on different scales.

The numerals 2 and 3 represent the stiles or sides of an opening adapted to be controlled by shutters as '1, 5 and 6. There are two of such shutters shown practically in full and one partially in Figs. 1 and 2. There may be one or any suitable number of these shutters. When closed they premovement.

vent the passage of air through the opening formed in part by the sides 2 and when open permit the flow of air through such openmg. \Vhen closed the beveled surfaces 7 of the shutters are opposite each other, the packlngs 8 carried on the beveled edges of the shutters being adapted to effectually exclude'the passage of air through the space between the shutters when the latter are closed. The shutters are shown as pivotally mounted, being provided at their ends with outwardly disposed cylindrical pivots, studs or pins 9, the studs or pins of the respective shutters being coaxial and being mounted in the present case for rolling These pivots or studs may be rigidly connected with the shutters in any desirable manner; for example their butts may be driven into bores in the respective shutters.

To support the pins or studs 9 the brackets or tracks 10 may be provided, these brackets or tracks 10 being of approximately U-form and being driven or otherwise tightly fitted in the transverse channels or grooves 11 in the stiles or sides 2 and 3. The ends or upright portions of these brackets or tracks 10 constitute stops to limit the rolling movement of the respective pins. It will be clear that owing to the rolling relation between the pins 9 and the respective supports 10 that each shutter is supported in an anti-friction manner. As represented one branch of each of the supports 10 is provided with an extension 12 equipped with a flange 13 to fit fiatwise against a surface of the cooperating side 2 or 3 and to be fastened suitably to said side as by screws 14.

Each of the shutters is shown provided with a projecting arm 15 cooperative with a suitable operating device as the trace or rod 16, the rod having transversely elongated slots 17 to receive the projecting pins 18 extending outward from the respective arms 15, this presenting a simple way of loosely connecting the operating device with the shutters. The pins 18 are perforated to receive the cotter pins 19 between which and the adjacent arms 15 the washers 20 are shown as disposed. By pulling down on the rod 16, the arms 15 will be correspondingly moved to swing the shutters 5,

6 and 4 open, the pins during such motion rolling on the bodies of their cooperating supports 10. By thrusting upward on the rod 16, the action is reversed so as to effect the closing of the shutters,

It will be noted that I provide means for supporting each shutter for floating movement, so that any one or more of the shutters can be tightly, and substantially closed regardless of the fact that it or they may have become Warped or buckled from use or the packing when present is worn. In the present instance the shutters are supported for swinging movement about a changeable axis, and as will be inferred the relations mentioned can be obtained in many different ways, although I have shown and described one which is highly advantageous and which has met my requirements. By reason of the connection between the actuator or operating device 16 or analogous member in a loose manner, I can compensate for these various changeable conditions.

It will be noted that the axes of move ment of the respective shutters, are within the boundaries thereof, said shutters being shown as mounted for oscillation, between their ed es. It will be further observed that the shutters swing in the same direction.

What I claim is:

1. Shutter mechanism comprising a shutter, and means supporting said shutter within its boundary for floating swinging movement.

Shutter mechanism comprising a shutter, and means supporting said shutter within its boundary for swinging movement about a changeable axis.

3. Shutter mechanism comprising a shutter, and means supporting said shutter between its edges, for floating swinging movement.

4:. Shutter mechanism comprising a plurality of shutters, means independently supporting the shutters, each for movement about a changeable axis, and means for swinging said shutters in the same direction.

The combination of supporting means and a shutter, and a pivot between the supporting means and the shutter having a rolling engagement with one of them, and

an approximately rigid connection with the other between the edges of the shutter.

(S. The combination of opposite supporting members, a shutter between the supporting members, the latter being provided with brackets, and pivots connected with and extending from the shutters between the edges thereof, the brackets supporting said pivots for rolling movement.

7. The combination of opposite supporting members, a shutter between the supporting members, the latter being provided with brackets, and coaxial pivots connected with and extending from the shutters, the brackets supporting said pivots for rolling movement, and having stops to limit the movement of the pivots.

8. Shutter mechanism comprising a shutter provided between its edges with outwardly extending coaxial pivots, and means supporting said pivots for rolling and turning movements.

9. Shutter mechanism comprising a plurality of shutters, means supporting the shutters for swinging floating movement,

each shutter having a projecting arm provided with a pin, a rod having transversely elongated slots to receive the pins, and means for holding the rod in assembled relation with the pins.

10. Shutter mechanism comprising a plurality oi shutters having outwardly extending coaxial. pivots between their side edges, side members between which the shutters are disposed, brackets supported by the side members and sustaining said pivots for rolling movement.

11. Shutter mechanism comprising a plurality of snutters having outwardly extending coaxial pivots between their side edges, brackets, side members between which the shutters are disposed, the side members being grooved and the brackets being rigidly fitted in the grooves and receiving the re spective pivots, the brackets having means to limit the rolling movement of the pivots.

In testimony whereoi l atlix my signature in presence of two witnesses.
